Police say an officer fatally shot a man who ran into a stranger's house and pulled a knife on the officer who followed him inside.

PHILADELPHIA (WTXF) - A Philadelphia police officer fatally shot a man who ran into a stranger's house and pulled a knife on the officer who followed him inside.

Spokesman Capt. Sekou Kinebrew says the incident took place just before 8:30 a.m. Wednesday, as officers responded to a report of a fight on Belgrade Street in Port Richmond.

One man identified as an instigator fled the scene and ran into a home. Inside was a woman about to take her child to school.

The officer, holding a Taser, told the man to show his hands, and that is when he brandished a knife. When the officer pulled out his firearm, the suspect allegedly lunged at the officer with the knife, prompting the officer to fire his weapon.

The suspect, who suffered a single gunshot wound to the chest, was transported to Temple University Hospital, where he succumbed to his injuries. Police have yet to identify the deceased.
